MINE-DOOR.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed November 14, 1904. Serial No. 232,619.

10 aZZ whom it may concern:

Be it known that we, ROBERT J GOOD and GEORGE E. HALL, citizens of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvementsin Mine- Doors; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the numerals of reference marked thereon.

The object of the present invention is to provide mechanism adapted to operate doors by means of the passage of the cars over the trackthat is to say, to provide mechanism by means of which the wheel or wheels of an approaching car will operate the door for the passage of the car and mechanism to close the door after the car has passed These objects are attained by the construction, mechanism, and arrangement illustrated in the accompanying drawings, in which- Figure 1 is a view of a portion of one of the track-rails and illustrating the oscillating bars and the door-operating arms. Fig.

2 is a top view showing aportion of one of the track-rails and the oscillating bars moved in position to open the door. Fig. 3 is a side elevation showing the oscillating bars and illustrating the top of the bar-operatin arm. Fig. 4 is a transverse section of a trac crail, showing the track-clamps and one of the oscillating bars, also showing a car-wheel in contact with the oscillating bar. Fig. 5 is a longitudinal section of a mine-gallery, showing the door-frame placed in proper position. Fig. 6 is a top' view of the track, showing a horizontal section of the doors and illustrating the door-operating mechanism. Fig. 7 is a transverse section of the track, showing the doors closed. Fig. 8 is a view showing the doors open. Fig. 9'is a transverse section I taken on line 6 6; Fig. 6.

Similar numerals of referenceindicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents one of the track-rails, which is held in proper position in the usual manner. To the track-rail 1 are attached the plates 2 and 3 by means of suitable clamping-bolts 4, Which plates are for the purpose of providing suitling-heads are able means for pivotally attaching the arms 5, which arms are provided at their upper portion with the Theads 6, these T-heads having rounded ends 7 for the purpose of being received in the ends of the oscillating bars 8.

For the purpose of providing bars that are light they are preferably formed of tubes, by which arrangement the rounded ends 7 of the T-heads 6 can be entered into adjacent ends of two adjacent oscillating rods or tubes, as illustrated in the drawings. 7

The extreme ends of the oscillating rod members farthest from the door are pivotally attached to the fixed heads 9,, which fixed heads are secured in any convenient and well-known manner, preferably to the flange of the track-rail.

The oscillating rods or tubes 8 are located in such relationship with the track that as a car approaches the flanges of the car-wheels come in contact with the proper rod member, and inasmuch as said rod members 8 are normally located at an angle to the track they will be swung so as to move the free ends of said members away from the trackdownward and brought under the track-rail,

as best illustrated in ment the levers 11 track-rail.

For the purpose of automatically opening the door as the car approaches from either direction, two door-operating levers 11 are provided, together with the different parts belonging thereto, which parts are duplications located upon opposite sides of the door.

To the free ends of the levers 11 are attached the coupling-heads 12, to which coupattached the links 13, and one of the links is attached to the downward-extending arm 14, which arm is preferably formed integral with the hub 15, securely at- Fig. 4, by which arrangeare entirely under the tached to the rock-shaft 16, which rockshaft extends under the track-rails and is at its opposite end provided with the hub 17. The hubs 15 and 17 are provided with the upright arms 18, to which upright arms are pivotally attached the door-opening links 19, which door-opening links are attached to the outer vertical edges of the doors 20. To the upper member 21 of the door-frame proper or its equivalent are attached the brackets 22, which brackets are extended some distance laterally from the door-frames. Directly below the brackets 22 are located the brackets 23, which brackets are secured to the topor upper ends of the doors 20, and the brackets 22 and 23 are pivoted together, by which ar rangement the top or upper door-hinges are formed or produced. To the bottom or lower ends of the doors 20 are securely attached the curved arms 24, which curved arms extend downward below the bottom of the door and have their lower ends brought below the track-rails 25. The bottom or lower ends of the curved arms 24 are pivotally connected to the brackets 26, which brackets are held in fixed position upon suitable framework or ties, as the case may be,

by which arrangement hinges are provided for the bottom or lower ends of the doors 20.

It will be understood that by hinging the doors at their top and bottom ends, as just above described, said doors can be brought into the position illustrated in Fig. 8, which is their open position, and atwhich time the car can pass through the doorirame.

It will be understood that as the car moves or approaches toward the door the rods 8 will be forced away from the track-rail 25, thereby oscillating the levers 11, which in turn rocks the arms 18 and pulls the door-opening links 19, and by reason of said door-opening links being pivotally attached to the doors 20 each door will be turned upon its hinges until the doors are brought into open positions or parallel with the track-rails 25. After the car has fully passed the oscillating rods or tubes 8 the arms 18 will be brought into their normal positions by means of the counterbalances 27, fixed to the rock-shaft 16.

Having fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

1. The combination of a track or way, a door-frame, doors hinged about midway be tween their vertical edges, oscillating tubes located in the path of the travel of the carwheel, arms provided with T-heads, the osc1llating tubes being fitted over the T-heads of the arms, and the arms prov'ded with extended levers, said arms and extended levers pivoted to their supports, a rock-shaft journaled below the track, link-sections between the rock-shaft and the arm-levers, and means for swinging the doors by the rocking move ment of the rock-shaft, substantially as and for the purpose specified.

2. The combination of a track or way, oscillating tubes located in the path of the travel of a car-wheel, arms provided with T heads at their free ends, said T-heads provided with rounded ends, and the rounded ends located in adjacent members of the oscillating tubes, levers extended from the arms, a door-frame having hinged thereto doors, and means intermediate the leverarms, and the doors adapted to swing the doors by the oscillation of the tubes, substantially as and for the purpose specified.

3. The combination of a trackor way, a door-frame provided with doors, the top or upper ends of the doors having brackets extended laterally from the doors, brackets secured to the upper portion of the door-frame, and the door-brackets and door-frame brackets hinged together, curved arms secured to the bottom or lower ends of the doors, said curved arms hinged in alinement with the upper door-brackets, oscillating tubes adapted to be operated by a car-wheel, and intermediate means for opening and closing the doors, substantially as and for the purpose specified.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
